Disguisting Service at Bidvest Bank

I flew to JHB to my horror was left stranded without any cash because my card was blocked which I only discovered on arrival at OR Tambo. I couldn't use my bank card to pay for my car rental (funny enough it was at Bidvest Car Rental) as well as not being able to buy anything to eat today!! At least the helpful people at the airline changed my flight so that I could go home where I at least have food to eat!

I was told by the customer service agent that "back office was investigating a transaction and while they do so, my account has been frozen. I have a legal document in support any transactions that have been made recently, but I guess this is not important

I find this TOTALLY unacceptable that the Bidvest in fact is *****ing my money and left me stranded!

I want recourse urgently
